What should I do if one of the main Menu buttons is not good after the phone is flooded.

The first time is self-repair, remember not to turn on, remove the battery, remove the mobile phone card, memory card, and mobile phone case, immediately use a hair dryer to resist blowing, tomorrow the sun comes out and put it under the sun, do not sun when the sun is too strong, easy to expose the screen, 2 days after the water evaporates before you can start the test, if there is a key confusion and the key is not effective, you also need to blow and dry, if there is no boot, and black screen, white screen, flower screen, need to repair shop to solve This is my many years of practical experience.

1: No matter what kind of water the phone falls into, you should directly remove the phone battery (instead of pressing the power off button) as soon as possible!

2: Use undusted napkins, cotton balls, cotton swabs, etc. to absorb all the water that can be wiped off outside.

3: If it falls into clean water, you can clean the phone with anhydrous alcohol, because the alcohol volatilizes quickly, and the water on the circuit board can be volatilized together (provided that you have anhydrous alcohol). If it falls into the sewage, it should be cleaned immediately, and the visible dirt should be cleaned first, and the impurities attached to the components should be brushed off with a brush.

4: Use a hair dryer to swing the dryer from a distance. (Be careful not to blow too close or to one place for a long time).

5: Keep the phone in a cool and dry place for 24 hours, if there is no hair dryer to dry the water, it is best to leave it for 48 hours.

6: Install a battery with sufficient power to test it, if it can't be turned on, then you have to take it for maintenance. Good luck to the landlord!

If you still have any questions, you can feel free to post questions at the Knowing Steel Seventh Company, and the Knowing Steel Seven Company team will answer them for you! Thank you.

I also used it, but I still went to repair it.

If you are using a Huawei phone.

It is recommended that you deal with the following troubles:

1. Please try to place your phone in a dry and ventilated place and use a paper towel to blot the water stains on the surface of your phone.

2. If the phone is turned on, press the power button to turn it off; If your phone is turned off, don't try to turn it on.

3. Please take out the SIM card and microSD card.

4. Please bring your smartphone to the Huawei Customer Service Center for testing and processing as soon as possible to avoid unnecessary losses.

Precautions: 1. Do not move or shake the mobile phone frequently after entering the water, so as to avoid the spread of moisture inside the mobile phone.

2. Do not use a hair dryer to blow or bake at high temperature (including microwave heating) after entering the water, so as to avoid the liquid being blown into the inside of the mobile phone and damaging the mobile phone at high temperature.

3. The mobile phone is made of precision electronic components.

There is a potential risk after water ingress, so please keep your phone turned off.

4. If you don't have a backup of your data.

There may be a risk of data loss when repairing.

The Apple phone is flooded, and the home button fails because the water ingress causes a short circuit in the phone's motherboard.

At this time, the following points should be noted:

1. If the water enters the mobile phone, it should be sent to the mobile phone repair station for ultrasonic cleaning as soon as possible.

2. If the battery is removable, disassemble the battery as soon as possible to reduce the corrosion of the internal components of the mobile phone caused by the electrolysis reaction. At the same time, it can also avoid the occurrence of the phenomenon of the inability to charge the limbs due to the short circuit of the circuit and the empty battery.

3. If it is not cleaned, the liquid will leave impurities attached to the components after the electrolysis reaction, and its electrical properties will be affected for a long time, such as leakage, poor contact, etc. In severe cases, it will also happen that the components or motherboard wires are dismantled and damaged by the collapse of the world.

If the home button fails in everyday life, you can use the small button for the auxiliary function instead of the home button.

1.Go to Settings General.

2.Select General Accessibility.

3.Select "assistivetouch" for accessibility.

4.Click the dot to the right of "AssistiveTouch" to turn on the feature.

Here are 5 ways to do this:

1. Open the back cover and dry it in a ventilated place reliably, but it takes a long time to return to the room.

2. Drying in the sun is relatively fast, but there may be other problems due to high temperature, and there may be water vapor.

3. Dry with a hair dryer, but water vapor may also remain.

4. Use 5 to 6 small packets of desiccant, wrap the mobile phone with some thin paper towels, generally 24 hours can be turned on with confidence, the time is fast, and the effect is good, but it is necessary to pay attention to prevent the desiccant from entering the mobile phone.

5. After drying the water as much as possible, you can remove the battery of the mobile phone and put it in the baking machine, and bake it below 40 degrees Celsius for about 15 minutes.

Is your phone still on when it's flooded? Aren't you afraid of a short circuit and burn out? Wrap your phone in a tissue and zoom in for a few days.

If the mobile phone is flooded, turn it off first and don't turn it on. Take it to a professional after-sales center to disassemble and repair.
